Chiller low evaporator pressure
WebDec 28, 2024 · During heat transfer, the refrigerant evaporates as it changes from a low-pressure liquid into vapor, reducing the process temperature. The compressor performs … WebThe evaporator is also known as cooler or freezer or chiller. It is connected in the low pressure side of the refrigeration system. It is installed in-between expansion device and compressor. Function of evaporator: ‘To absorb the heat from the substance or space, which is to be cooled, by means of refrigerant’.
Chiller low evaporator pressure
Did you know?
WebThe refrigeration cycle starts with a low-pressure liquid/gas mix entering the evaporator. In the evaporator, heat from the process water or water/glycol solution boils the refrigerant, which changes it from a low-pressure liquid to a low-pressure gas. The low-pressure gas enters the compressor where it is compressed to high-pressure gas. WebFeb 20, 2024 · 5. Open the expansion valve too small. The expandable valve is used to throttle the high-pressure liquid refrigerant into a gaseous state. If it is too small, the …
